Study the following graph and answer the question below.

Total investment(in ₹ thousands) of Vivek and Shalini in six savings schemes.

Percentage of Vivek's investment out of total investment

What is the ratio of the total amount invested by Vivek in schemes A and C together to the total amount invested by Shalini in schemes A and C together?

26 : 29

Total investment in A = 80000

Total investment in C = 30000

Investment of vivek in A = \(\frac{50 }{100 }\) × 80000 = 40000

Investment of vivek in C = \(\frac{40 }{100 }\) × 30000  = 12000

Now , Investment of shalini in A = 80000 - 40000 = 40000

Investment of shalini in C = 30000 - 12000 = 18000

Ratio of investment of vivek in A & C  :  Ratio of investment of shalini in A & C

( 40000 + 12000 )  :   (  40000 + 18000 )

      520000            :          58000

           26               :             29
